1 Preliminary Analysis Between FIFA World Cup 2014 Winning and Losing Teams Goal Scoring Characteristics Muhamad Noor Mohamed, Mohd Saufi Dali, Muhamad Safiq Saiful Annur, Nurul Fizan Sidek, Mardiana Mazaulan, Mohd Hanifa Sariman and Mohd Zulkhairi Mohd Azam Abstract This study was conducted in order to determine the differences in terms of scoring characteristics between winning and losing teams in FIFA World Cup matches were selected to be observed. The indicators chosen for this analysis were the pitch area where goal was scored, goal scoring time, and the position of player who scored the goal. Wilcoxon test used to prove the differences between winning and losing teams. Winning team scored most of the goals in the second half (68 goals) of the match compared to the first half (48 goals). In the first half of the match, there were significant differences in scoring time between winning and losing teams in 0 15 min (Z = 3.00, p < 0.05) and min (Z = 2.982, p < 0.05). In the second half of the match, the scoring patterns increased with time for the winning team; 15, 24, 30, and six goals during 45 60, 61 75, min, and extra time, respectively. Significant differences in the scoring time between the teams were observed in the second half of the match, min (Z = 3.386, p < 0.05), and min (Z = 3.403, p < 0.05). In addition, there were significant differences between winning and losing teams in all pitch areas; inside goal box (Z = 3.154, p < 0.05), outside penalty box (Z = 2.357, p < 0.05), and penalty zone noted the highest tally for the winning teams (Z = 5.230, p < 0.05). Finally, striker scored the most goal for both winning (69 goals) and losing (20 goals) team (Z = 4.862, p < 0.05) as well as the midfielder (Z = 3.139, p < 0.05). As for the winning team, the defender also managed to scored goals (16 goals) (Z = 3.557, p < 0.05) compared to no goal for M.N. Mohamed (&) M.S. Dali M.S.S. Annur N.F. Sidek M.

Keywords Football Goal Scoring Winning Losing Team Analysis 1 Introduction The study of players and team is very important for the management team to increase their own team performance. Nowadays, the advancement of modern technology enables the coaches and team management to understand and evaluate their athlete s performance. Thus, the study on performance analysis helps to increase the opportunity to understand their team better. In order to get the correct data from the tournament, performance indicators play major role to help coaches and management team to further enhance the strategy of their team. These indicators can help to predict the past, present, and future performance levels of the athletes. Besides, the indicators also serve as a mirror of the athletes shortcomings in sports. Performance indicators can be defined as the selection and combination of variables that defined the variables of performance and simultaneously help athletes and coaches to achieve their goals [1]. In order to form a good football/soccer team, it is best for a coach to gain some resources and external information [2]. Feedback from the performance analysis is an important component of the coaching process and become information source for both players and coaches [3]. Crucial analysis toward the shots delivered is increasing the winning rate of a team. Furthermore, having good players with the ability to control the ball and scored goal is valuable to their teams [4]. The team is at advantage when goals are scored against its opponent. Even, the spectators evaluate the teams as a good team when that team is able to score many goals. The goals in football can be explained as the main factor or the achievement of the teams [5]. Nowadays, the findings that have been found by the researcher on the performance analysis help the coach and the team management to create a good training program [6]. Hughes and Franks stated that, the difference between successful and unsuccessful teams is the ability of the teams that can lead the possession of shots on goals [7, 8]. The higher the number of shots made, the higher the rate of opportunity to get the goals. 2 Method 2.1 Sample This study analyzed 51 matches from the FIFA World Cup 2014 using recorded video. The data were collected from the matches that end up with the result of winning and losing. All matches ended with draw was excluded from this analysis.

3 Preliminary Analysis Between FIFA World Cup 2014 Winning 193 Table 1 Variables studied Variables Performance indicators Variables Pitch area where the goal was scored Time the goal was scored Position of the scorer Among the match that were also included were matches which ended with extra times, but ended as draw in knockout phase. This tournament was selected because it was major benchmark tournament for soccer teams performance and the biggest tournament in the world where all top-notch country who qualified participated in the match. Making it the most high-performance game compared to others. All participating teams also had a world ranking approved by FIFA (Table 1). 2.2 Procedures All the matches were analyzed by viewing the highlights of all the 51 matches that end up with the result of winning and losing. The remaining 13 were excluded as the scores were draw. The 51 matches were separated into two categories which were winning teams and losing teams. The winning teams were the teams that end up the match with the result of winning and the losing teams were the teams that end up with the result of losing. Data were obtained using hand notational analysis by the help of Dartfish Easy Tag software for android phone (Dartfish Ltd., version 1.0.8) during the period of viewing the video. To ensure enough processing power, this software was operated using ASUS device (ZenFone 6, Android 4.3, Intel Atom Z GHz, ASUSTek Computer Inc., Taiwan). The software was set according to the preferred indicators before starting analysis. All the variables intended for the study were coded in this software. Upon viewing the video, researcher clicks on the appropriate button during the occurrences of the action. All related information such as the numbers of action occurred during the recording was given by the software. 2.3 Reliability Testing Inter- and intra-tester reliability testings were carried out in order to determine the reliability of the produced data. A gap of five-day period was considered between each data collection in order to prevent any memory retention from previous data collection to prevent biasness which can disrupt the process. Inter-tester test was performed by two different testers, and their results were compared to calculate the reliability of the testers. Allowable error limit was considered limiting within 5 % [7, 8].

4 194 M.N. Mohamed et al. 2.4 Data Analysis Descriptive statistics was used in order to analyze the performance indicators. For the inferential statistics, nonparametric statistical test Wilcoxon signed-rank test was used to investigate the significant differences of the performance indicators. Within-group analysis for the winning team was carried out using Friedman test, and post hoc test was carried out using Wilcoxon signed-rank test to seek the differences within the group. All statistical data were analyzed by using the Statistical Package for the Social Sciences version 22 (SPSS ver. 22.0). Significant value was set as p < Result A total of 123 goals were scored by the winning teams and 32 goals by the losing teams. Figure 1 shows that there was significant difference between winning team and losing team regarding time of scoring in the first half (Z = 4.017, p < 0.05). Two segments of total time of 0 15 min (Z = 3.00, p < 0.05) and min (Z = 2.982, p < 0.05) were obtained for the significant difference between winning and losing. The time segment min was discarded as it did not reach statistical significant level (Z = 1.661, p > 0.05). On the other hand, there was significant difference between winning and losing teams during the second halves (Z = 5.047, p < 0.05). Only three segments of the total time showed significant differences for the second halves of the matches, which were min (Z = 3.386, p < 0.05), min (Z = 3.403, p < 0.05), and extra time (Z = 2.000, p < 0.05). The time segment if min did not reach statistical significant state (Z = 2.357, p > 0.05). Goal scoring patterns are shown in Fig. 2. Within-group analysis was carried out for the winning teams as presented in Fig. 3 shows that all three segments for the first halves did not show any significant Fig. 1 Segment of time goal being scored by winning and losing teams

Open square denotes significant difference with 76- to 90-min segment (p < 0.05); filled diamond denotes significant difference with extra time segment (p < 0.05) differences. For the second halves of the match, there was a significant difference in the segment of goal scored (N = 51, chi-square = , p < 0.05). Post hoc test showed that there was a significant difference in time segment the goal was scored between 45 to 60 min and 76 to 90 min (Z = 2.473, p < 0.05), 61 to 75 min and extra time (Z = 2.509, p < 0.05), and between 76 to 90 min and extra time (Z = 3.350, p < 0.05). Based on the descriptive statistics (Mean ± standard deviation) the highest number of score was scored during 76- to 90-min segment (0.59 ± 0.431). Significant differences are observed for the second variable which is pitch area between winning and losing teams. The observed differences are goal box (Z = 3.154, p < 0.05), penalty box (Z = 5.230, p < 0.05), and outside of penalty box (Z = 2.357, p < 0.05) (Fig. 4). Within-group analysis was carried among the winning team as presented in Fig. 5 showed that there was significant difference between pitch areas (N = 51, chi-square = , p < 0.05). Post hoc test revealed significant differences

Open square denotes significant difference with penalty box (p < 0.05); filled diamond denotes significant difference with outside penalty box (p < 0.05) between goal box and penalty box (Z = 4.330, p < 0.05), goal box and outside the penalty box (Z = 2.306, p < 0.05), and also penalty box and outside of penalty box (Z = 5.021, p < 0.05). It was found from descriptive statistics (Mean ± standard deviation) the highest number of goals was scored from the penalty box (1.63 ± 1.326). The last variable analyzed was the player position that scored the goal. Figure 6 further illustrates the differences in goals scored according to the position. There were significant differences of player positions between winning and losing teams. The positions were striker (Z = 4.862, p < 0.05), midfielder (Z = 3.139, p < 0.05), and defender (Z = 3.557, p < 0.05). However, scores obtained by own goals not reach statistical significant level (Z = 1.000, p > 0.05). Within-group analysis for the winning teams presented in Fig. 7 showed significant differences between the position of scorers (N = 51, chi-square = , p < 0.05). Post hoc test acknowledged that there were significant differences

Open square denotes significant difference with midfielder (p < 0.05); filled diamond denotes significant difference with defender (p < 0.05) between striker and midfielder (Z = 3.902, p < 0.05) and striker and defender (Z = 4.702, p < 0.05). However, there was no significant difference between midfielder and defender (Z = 1.923, p > 0.05). From descriptive statistics (Mean ± standard deviation), the highest number of goals was scored by the strikers (1.35 ± 1.055). 4 Discussion In this study, the first variable that we examined was on the pitch area where the goal was scored. Previously, there were three common areas where the players can score the goals: the goal area, penalty area, and outside of penalty area. For this

8 198 M.N. Mohamed et al. study, we found that most goals were scored from penalty box (Mean ± SD, 1.63 ± 1.326). This showed that the penalty box was the main area where the shots were made by players. This is supported by the result from past research which showed that most of the goals came from the area of penalty box [9]. In this range, the player is more confident compared to goal box which is near to the goalkeeper and outside of penalty box that was too far from the goal post. Study [7, 8] stated that when the player was not in the goalkeeper area, the player can make shots with added comfort. Penalty area was the best area that has higher opportunity to score the goal compared to the goal area and outside of penalty area. Finding found that 86 % of balls passed into the area then into the penalty have higher opportunity to score the goals [10]. A study done at European Championship 2004 showed that 44 % goals scored from the penalty area, 35.2 % goals scored at the goal area and 20.4 % scored outside of penalty area [11]. The second variable we observed was on the segment of time the goal was delivered. By looking at the winning team, it can be concluded that there was a significant difference between the first half and the second half of matches. In this research, the result showed that there were more goals scored during the second half compared to the first half of the matches. This is because, there was an increase to attempt to score as many goals as they can before the final whistle is blown. Past study also stated that most goals scored at the first 15 min in the second half that were between 45 and 60 min [12]. However, in our analysis, we only investigate that the time goal was scored but not differentiating between the winning and losing teams. Study by [7, 8] found that most of the winning teams score at the last 15 min between 76 and 90 min and the losing teams scored at the min during the first 15 min after the second half started. The current data prove that the winning teams were able to score more goals at the last 15 min and this is supported by the previous research [13]. This happened due to the psychology and physical condition which cause bad performance and early exhaustion before the end of the match [7, 8, 11]. The best solution to overcome this shortcoming is to increase the fitness level of the teams. According to [14], most of the goals scored at the end of the match were influenced by the mental and physical fatigue. Reilly reported that in Scottish League , average scoring rate was at the final of 10 min of play [2]. Armatas stated that statistically, more goals scored in the second half of the matches and the last 15 min in the three latest World Cup matches [9]. Final variable examined was on the position of the player that scored the goal. The most number of goals was scored by the striker. However, we discovered that the defenders from the losing team slightly assisted in the aspect of scoring goal compared to the winning teams. Based on the previous study, most goals were scored by the striker and midfield for both winning and losing teams [7, 8]. However, there were no significant difference of own goals because this was not the main attention, and both winning and losing teams contributed to others goal tally. The attackers from both winning and losing teams had scored more goals compared from other position. This is because the players of this position were agile so they were able to respond quickly to the situation. [7, 8]. The decision making is also important and this has been shown from the previous study that stated awareness

9 Preliminary Analysis Between FIFA World Cup 2014 Winning 199 can support the position of midfield in how they select the correct action in situation of attacking and defending [15]. A study [16] stated that striker had the most opportunity in shooting toward goal and performed some skill to overcome the defender, the midfielder had the most in dribbling and defenders had the most in tackling. This can be said why the striker from this research is the top in scoring the goals compared to midfielder and defend position [17]. 5 Conclusion We showed that most of the goals scored by both winning and losing teams were at the penalty area which was not too near to the goalkeeper position and also not too far from the goal post. We also provided the evidence on time the goal was scored. The winning teams and losing teams scored most at the goal during the last 15 min, which was during the 76- to 90-min segment. Finally, we showed the position of the goal scorer. Most of the goals were scored by the strikers of the winning and losing teams. Therefore, with evidence provided, it is advisable for coaches and team s management to: (a) Develop a training program that focuses more on the last 15 min of the match due to the fact that it was the time where more goal attempts being made. (b) Incorporate psychology and physical conditioning in future training program to ensure their team is able to concentrate to the game until the end of the match. (c) Train more on penalty box distance, due to the fact that most of the goals tried and scored were from this distance. (d) Focus more shooting drills to the striker. Nevertheless, other positions also need to train on shooting to increase the chances of goals. References 1. Hughes MD, Bartlett RM (2002) The use of performance indicators in performance analysis.
